Tokyo police has served another arrest warrant on Mark Karpelès; the World Wide Web Consortium prepares to launch a Web Payments Working Group and more top stories for August 21.

World Wide Web Consortium to Launch Web Payments Working Group

The World Wide Web Consortium (W3C), led by World Wide Web inventor Tim Berners-Lee, prepares to launch a Web Payments Working Group by the end of September.

The W3C announcement states:

“The Web Payments Working Group is not creating any new digital payment schemes, but rather integrating existing and emerging schemes more efficiently and securely into Web applications […] A standardized message flow should make it easier to automate payments, which will improve the overall security and user experience of making payments on the Web.”

The W3C Web Payments documentation references bitcoin and cryptocurrencies alongside other online payment means such as Google Wallet, Apple Pay, PayPal and iDEAL.

Mark Karpeles Re-Arrested in Japan

Tokyo police has served another arrest warrant on Mark Karpeles, the CEO of failed bitcoin exchange Mt Gox, suspecting he misappropriated ¥321 million (US$2.6 million) of customer deposits into other personal projects. The funds were allegedly spent on purchasing software rights and a US$48,000 bed.

Karpelès lawyer denied the allegations, stating:

“The deposits were used for investments in new businesses while the bed was purchased as interior decoration for his guesthouse, both of which were meant as marketing tools to promote the use of bitcoins […] Despite the long detention period, the fact that investigative authorities could only come up with these reasons to make their case for embezzlement is evidence that Mark was not involved for personal reasons in the disappearance of massive cash and bitcoins.”

Bitmain Head of North America Jake Smith said:

“The BM1385 chip represents more than six months of full time research and development work from our chip design team, so it required a significant effort to produce. This being our first full-custom chip design, it took a lot more work than previous chips we’ve put out.”

Donald Trump Vows to Clamp Down on Mexican Remittances

American real estate mogul and presidential hopeful Donald Trump has announced his intentions to impound all remittance payments derived from illegal wages. If Trump’s immigration plan ever goes through, it will likely create a disastrous working environment for any foreign immigrants in the U.S. and will increase the transaction fees of remittance outlets, which are already taking a large cut of the migrants’ earnings. Unless, of course, bitcoin can offer a solution.

Harborly Bitcoin Exchange Shuts Down

Texas-based bitcoin exchange Harborly has announced to shut its doors as a result of work on a separate project that co-founder and CEO Connor Black described as “a growth hacking tool and service” currently in private beta.

Black explained:

“We made the decision to close down Harborly around the time we started seeing results with a side project we had been working on internally. Given the nature of the project, we realized that 1) we have to move as fast as possible on it, and 2) we don't have enough resources to continue doing both.”
